Answer:
a) Para
, hay 13 flores en la fila 4.
b) Para
, hay 22 flores en la fila 7.
c) La fila 11 tiene 34 flores.
Step-by-step explanation:
De acuerdo con el enunciado, cada fila tiene tres flores más que la fila inmediatamente anterior, significando que se puede determinar el número de flores de cada fila mediante una serie aritmética:
,
(1)
Donde:
- Índice de la fila de flores.
- Número de flores del índice de la fila de flores.
a) Para
, hay 13 flores en la fila 4.
b) Para
, hay 22 flores en la fila 7.
c) Si
, entonces el índice de la fila es:


La fila 11 tiene 34 flores.
We will use formula for circumference of circle:
lets name it as O
O = 2*r * pi
when we express r in this formula we get:
O = 2*2.2*pi
O = 4.4*pi
From this we can see that for given radius, answer is 4.4. The formula only depends on pi and that is what "in terms of pi" means.
Answer and Step-by-step explanation:
7. 70 - 180 = 110
8. 39 - 180 = 141
9. 81 - 180 = 99
10. 81 - 180 = 99
11. 115 - 180 = 65
12. 41+36 = 77 - 180 = 103
x = answer
Answer:
it is a relationship where the first difference is equal and the second difference is 0
Answer:
Part A)
1) 
2)
Part B)
1) 
2)
Step-by-step explanation:
Part 1) x and y vary inversely and x=50 when y=5 find y when x=10 what is k?
we know that
A relationship between two variables, x, and y, represent an inverse variation if it can be expressed in the form
or 
step 1
<u>Find the value of k</u>
x=50 when y=5
substitute the values
------>
-----> 
The equation is equal to
or 
step 2
<u>Find y when x=10</u>
substitute the value of x in the equation and solve for y
Part B) x and y vary directly and x=6 when y=42 find k what is y when x=12
we know that
A relationship between two variables, x, and y, represent a direct variation if it can be expressed in the form
or 
step 1
<u>Find the value of k</u>
x=6 when y=42
substitute the values
------>
----->
The equation is equal to
or
step 2
<u>Find y when x=12</u>
substitute the value of x in the equation and solve for y
